Hi Stefan, I just checked on WSPRnet and red you got plenty of reports from your QRP activity so my 3 spots are a drop in the sea.. but 3 spots: Timestamp Call MHz SNR Drift Grid Pwr Reporter RGrid k

Hi MF, Thanks to the many spotters and the discussion. Indeed, there were 53 stations detecting the signal. Those are the ones above 1000 km distance Timestamp Call MHz SNR Drift Grid Pwr Reporter RG

Hi Stefan, Congrats on your results with the small indoor loop! You may want to take a close look into the WIMA data sheet. There are charts showing maximum permitted Vrms vs. frequency. I think you

Hi Paul, Oh yes, you are right, i forgot that. In the same way they could limit the maximum current at a given frequency and capacity... But this is probably to keep a certain life time and guarantee

Hi Stefan, Yes I am sure that is true about the capacitors. I did destroy a few operating with applied voltage about half way between the datasheet derated maximum for the frequency and the full AC v
